What the TEM255606 Is — and What It Fits

The TEM255606 (cross-referenced as CO-11159T) is a 100% brand-new A/C compressor — not a remanufactured unit — built as a direct bolt-on replacement for select 2.4L Mitsubishi models. It arrives with the full electromagnetic clutch assembly pre-installed, so the job is: mount it, service the system, charge it, done.

You can order it on the TEM255606 product page at Koeep.

Fitment chart

The 2011 Endeavor 3.8L uses the same compressor type, but it is a secondary application — verify fitment before you buy if that's your vehicle.

Run a wider year range or a 3.8L engine? The ECCPP A/C compressor for 06-12 Mitsubishi Endeavor, Galant and Eclipse covers both the 2.4L and 3.8L, which helps if your build date sits right at the edge of the chart above.

Technical Specifications

These are the numbers that matter when you're matching a compressor to your car:

OEM and aftermarket numbers it replaces

Before you order, match these against the sticker on your old compressor or your dealer's records. The TEM255606 replaces all of the following part numbers:

MN185233 • MR513358 • MSC105CA • 275847 • TEM255606 • TEM275847 • 140160C • 140160NC • 0610253 • 7813A325 • CO-11159T

Five Signs Your Compressor Is Done

• ❄️ Warm air from the vents. The compressor can't pressurize the refrigerant, so heat never leaves the cabin.
• 🔊 Grinding or squealing up front. Worn bearings or a failing clutch assembly generate abnormal noise from the compressor area.
• 🔄 The clutch never engages. The electromagnetic clutch won't lock in, so the compressor never cycles.
• 💧 Refrigerant leaks. Visible oil residue or UV dye around the compressor shaft seal points to failed internal seals.
• ⚡ Blown fuses or a tripping A/C relay. A seized compressor draws excessive current through the circuit.

Any one of these justifies a replacement. Keep running a failing compressor and it can shed debris through the entire A/C system — which turns a simple parts swap into a full system rebuild. Current stock and fitment details are on the Koeep product page.

Installation Steps That Protect the New Unit

On the 2.4L Galant and Eclipse, the physical swap is a straightforward bolt-on job. The steps below are what separate a compressor that lasts from one that dies within a month:

1. Flush the system. Clean the A/C lines, condenser and evaporator to remove debris and old oil left behind by the failed compressor.
2. Replace the receiver-drier or accumulator. This part traps moisture and contamination — reuse it, and both go straight into your new TEM255606.
3. Replace the expansion valve or orifice tube. A clogged metering device starves the new compressor of proper refrigerant flow.
4. Add the correct oil. The MSC105 compressor runs on PAG 46. A dry system typically needs 150-180 cc; check the pre-charge before adding more.
5. Pull a deep vacuum, then recharge. Draw the system down to 500 microns or lower and hold it for at least 30 minutes before charging with R-134A — typically 21-25 oz for these models.

New vs Remanufactured vs Used

Here's where your money actually goes across the three options:

Bottom line: a reman unit only gets fresh seals and bearings if the rebuilder decides they need them. A junkyard compressor carries no warranty and an unknown history. The new TEM255606 from Koeep ships with new Viton seals, new bearings and a complete clutch — so you do this job once.

More Parts for Your 2.4L Mitsubishi

The Galant and Eclipse share a platform, so while the front of the car is apart, it pays to check the rest of it:

• Timing belt and water pump kit guide — a complete maintenance walkthrough for the 2004-2009 Lancer and Eclipse 2.4L, if your belt service is coming due.
• Front-left CV axle — fits the 2006-2012 Eclipse and the 2007, 2009-2011 Galant 2.4L; worth inspecting while the car is on jack stands for the compressor job.
• AC & Heating collection — the full climate control catalog for cars and motorcycles, if you need anything beyond the compressor itself.

The Bottom Line

If you own a 2004-2012 Galant or a 2006-2011 Eclipse with the 2.4L engine, the TEM255606 is the direct answer: OEM-spec fitment, a complete clutch assembly, R-134A ready, new seals and bearings, and a 1-year warranty behind it all.
